In working towards ways of reading Mann, so that his own advances in suggesting new perspectives will become more vivid, I do some fairly standard philosophical analysis of ideas in Nietzsche and Schopenhauer.

The result can be quite new - perhaps a tendency to judge that something we've never conceived of is possible, or to feel sympathy for a trait or a type of person whom we've regarded with indifference or even hostility.

The classical allusions and the Platonic disquisitions on beauty are no longer a form of cover, but integral to Aschenbach's complex sexuality. Moreover, the wandering around Venice in pursuit of Tadzio isn't a prelude to some sexual contact for which Aschenbach is yearning.

Even though I want to expand the number of ways in which skilful ironic play happens, I suspect I'm probably guilty of the same shortcoming - and I hope that, one of these days, someone will claim that my book, while it goes in a salutary expansive direction, doesn't go far enough, that there are assumptions I make that show I've missed aspects of Mann's irony and ambiguity.

Aschenbach is not only a projection of Mann in the obvious ways - same daily routines, author of the works Mann had planned - nor even in sharing his author's aspirations, doubts, and sexual identity. His watchword, "Durchhalten!" [persevere, keep going] could be Mann's own.

In the end, we learn about the most basic philosophical questions - like "How to live?" - from a broad mixture of sources, including literature and philosophy, history and anthropology. These sources can guide our reflections on our own experiences, as we explore and reconsider. Mann contributed to such explorations in a distinctive way, and I hope my book brings that out.

In my current work on global warming, I argue that the only apparent solution to the deep problem of climate change would require very large transfers of wealth from rich nations to poor nations, so that the entire world can make the transition to renewable forms of energy as fast as possible.
